RC19208AGNA#BB0

Overview

The RC19208AGNA#BB0 is a PCIe Gen7 compliant clock multiplexer manufactured by Renesas Electronics. It functions as a 2:8 QMUX with differential LVDS or HCSL inputs and LP-HCSL outputs. The device operates on a single 3.3V supply (2.97V to 3.63V) within an industrial temperature range of -40°C to 105°C. Key electrical parameters include a maximum frequency of 400MHz, typical power consumption of 250mW, and ultra-low additive phase jitter. It is housed in a 48-VFQFPN package measuring 6mm x 6mm.

Feature Summary

• PCIe Gen7 compliant 2:8 clock multiplexer backward compatible with earlier generations
• Ultra-low additive phase jitter for improved design margin
• Supports LVDS and HCSL input signaling with LP-HCSL output
• Integrated automatic clock parking (ACP) and flexible start-up sequencing

Applications

• Cloud computing infrastructure
• High-performance computing systems
• NVMe storage controllers
• Network accelerators

Procurement Notes

Verify the specific suffix #BB0 against official documentation to confirm tray packaging and moisture sensitivity level requirements. Ensure compatibility with the 48-VFQFPN exposed pad thermal management specifications during integration. Confirm RoHS compliance status through current manufacturer declarations before procurement.

Selection Notes

Select this component for designs requiring low-jitter PCIe clock distribution up to Gen7 speeds. Verify that the system supports the required 3.3V supply voltage and that the 400MHz frequency range meets signal integrity needs. Consider the 48-VFQFPN package dimensions for PCB layout constraints and thermal dissipation requirements.
